IB Economics HL Internal Assessment Example

The diagram is relevant to the article and shows the main tariff mechanism clearly.

Key elements such as world price, tariff-inclusive price, domestic supply, demand, and world supply are included.

The diagram is used to support your argument rather than appearing as decoration.

The horizontal axis is mislabeled as quantity of imports, even though the quantities shown are domestic quantities.

The welfare areas are not individually identified as tariff revenue and deadweight losses.

The import quantity should be shown as the gap between domestic demand and domestic supply at each price, not as the axis itself.

Economic terminology is used consistently and appropriately throughout the commentary.

Terms such as tariffs, protectionism, world price, trade deficit, tariff revenue, and deadweight welfare loss are integrated into the analysis.

The terminology helps develop the argument rather than being included as isolated definitions.

A few places would benefit from even tighter precision, especially when distinguishing related outcomes such as tariff revenue and producer surplus.

The explanation of imports could be made clearer by using explicit numerical gaps between domestic demand and supply at each price.

Some comparative language, such as nominal versus real improvement, could sharpen the discussion of trade performance.
